In the new tab, you will see a page full of Wiki code; copy everything below "END INSTRUCTIONS" to the clipboard.

In the new tab, edit the page URL:

Replace ?title=ExampleFilter&action=edit with /YourFilterName

Your filter name should be one word - no spaces - but this is not mandatory.

First letter must be UPPERCASE due to Wikicode requirements.

Don't forget to remove the "?" and replace it with "/"

Hit Enter. If the title is already in use, you will be taken to that page.

If the page already exists, hit your browser's Back button.

Try a different title: Rename your filter, or add a suffix like "/CoolFilter (updated)"

If your title is unique, you will be greeted with the "There is currently no text in this page" banner. Click on the "edit this page" link.

Paste the source code you copied in Step 2.

Areas that need your attention are marked with HTML comments <!-- like this -->. Fill in as much information as you can. Leave the rest.

Click the Show Preview button to see how your page will look.

Click the Save page button to create the new page.

If you did something wrong, Click the Edit tab and fix it.

Please don't worry about formatting or incomplete information; just do the best you can.
A more experienced user will come along and clean up the page for you, and add a link to your page @External filters(don't do this yourself).

(Hmmm, I suppose you could submit documentation for a filter or script even if you aren't the author...)

*EDIT: you need to register to edit on this wiki - there is no anonymous editing like there is on Wikipedia.

I am unable to proceed. As per instructions I have replaced
#* Replace '''?title=ExampleFilter&action=edit''' with
#* '''/AdaptiveMedian'''
and hit enter. Nothing happens. In preview I see the name.
Am I doing something wrong?
